Description Roland Baudin 2015-11-20 14:54:03 UTC 
LibreOffice 5.0.2.3 crashes on Windows when executing this simple macro (which purpose is to get and manipulate the clipboard content):

Sub Main
	Dim oClip as Variant, oClipContents as Variant, oTypes as Variant
	oClip = createUnoService( "com.sun.star.datatransfer.clipboard.SystemClipboard" )
	oClipContents = oClip.getContents()
	oTypes = oClipContents.getTransferDataFlavors()
End Sub

*and* when the clipboard is empty.

To reproduce:
1. reboot Windows to be sure the clipboard is empty and to be in a safe state
2. lauch Writer and execute the macro
3. you should expect a crash, immediately or after a few seconds, or when pressing a key

If the clipboard is not empty at step 2, then there is no crash.
On Linux (Ubuntu 15.10), there is no crash even when the clipboard is empty.

Roland, please test with dev version. http://dev-builds.libreoffice.org/daily/master/
Thank you

OK, I tested with the dev version (build id below) and I expected no crash. I did several tests, with clipboard empty or not empty, and definitely no crash.
So I guess the bug is fixed...
Thanks!
